The jam doesn't even taste remotely like blueberries. Just very sugary artificial taste (even though it doesn't have artificial ingredients).
I was hoping for naturally tasty blueberry jam but was very disappointed. Should have noticed that it has 50% sugar.
True home-made blueberry jam usually has 0-5% sugar and the rest is pure wild blueberry. Too bad you can't get it any other way than picking the blueberries from the forest and making the jam by yourself. :(
